摘要：

The　3rd　generation　partnership　project　(3GPP)　long　term　evolution　(LTE)　standard　has　adopted　orthogonal　frequency　division　multiplexing　access　(OFDMA)　in　downlink　and　single　carrier　frequency　division　multiple　access　(SCFDMA)　scheme　for　the　uplink　transmissions,　which　utilizes　single　carrier　modulation　and　frequency　domain　equalization.　In　this　paper,　we　proposed　a　Raised　Cosine-like　companding　scheme　to　reduce　the　peak-to-average　power　ratio　(PAPR)　of　SCFDMA　signals.　The　proposed　scheme　can　transform　the　original　SCFDMA　signals　into　Raised　Cosine-like-distributed.　Moreover,　the　scheme　can　compress　the　large　signals,　while　maintaining　the　average　power　constant.　Computer　simulation　results　show　that　the　proposed　companding　scheme　can　offer　better　PAPR　reduction　by　properly　choosing　the　parameters.　©　2010　IEEE.
